fix missing barrier instructions in mips atomic asm
previously I had wrongly assumed the ll/sc instructions also provided memory synchronization; apparently they do not. this commit adds sync instructions before and after each atomic operation and changes the atomic store to simply use sync before and after a plain store, rather than a useless compare-and-swap. (cherry picked from commit bcad48439494820989f5867c3f8ccfa6aae2909f)
